Occasionally an alarm sounds on our eb17b funace. A label mentions something about an attic fan needing servicing. We don't have an attic. There is a hose above the funace that goes to the roof. Is there a sensor up there that needs servicing?

Is this a mobile home? I believe it has to be since you have the air make up unit,

Go to the sire below and register. Then post your question with your EXACT model number under Coleman. They will assist you with your problem and if you need a part they might have it since mobile home parts are sometimes hard to find.

Coleman eb17b electric furnace heating element staying on all the time... already changed sequencer... the doublewide heats up fine but when house reaches thermostat setting and unit shuts off the heating element stays on.
